T aZZ whom it may concern.-

Be it knownthat 1, JOHN GOTTLANDER, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Graders;

and I do declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art [0 to which it appertains to'make and. use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a toward the right, shown on alarger scale,

Fig. 4 is a section taken onthe line y 3 Fig. 1, looking toward the left, shown on a larger scale. Fig. 5 is a side elevation illustrating the means for controlling the rear extremity of the plow-beam, the parts being shown on a larger scale. Fig.6 shows the depending guide-bracket viewed in a direction at right angles to Fig. 5. Fig. 7 is a rear elevation of the machine viewed in a direction opposite Fig. 3. Fig. 8 is a perspective view in detail of the plow detached from the beam. Fig. 9 is a side elevation, partly in section, showing the forward end of the frame and plow-beam. 0 This is a distorted view. Fig. 10 is a top view of a portion'of the same construction. Fig. 11 is a section taken through the forward extremity of the plow-beam where the vertical bar A passes therethrough. Fig. 12 is a sec- 5 tion taken through the carrier fabric and one of the bent cross-bars of the carrier 66.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the upper longitudinal framework of the machine. As

shown in the drawings, the forward part 5 of this framework consists of a single bar, while its rear part is bifurcated and consists of two separated arms 5. The forward extremity of the part 5 is made fast to a rectangular front frame 6, consisting of vertical side bars 6 and horizontal top and bottom bars 6 and 6, respectively. The front part of the machine is supported by wheels 7, journaled on stub-axles 8, whose inner extremities are provided with vertical standards 9,

upon which the rectangular frame 6 is verticallymovable. The sides 6 of the frame are open to receive the bars 9, which are slidable therein The lower part of each bar 6 is slotted on the outside, as shown at a, to make room )1 the inner extremity of the axle as the frame moves vertically. The lowerpart of each bar 6 is also slotted on the inside, as shown at 0. Through each slot 0 is passed a bolt 10, which is made fast to a vertical bar 9. To each bolt 10 is secured one extremity of a chain 12, which passes downwardly under a pulley 13, mounted on the lower part of the frame 6, thence upwardly over a pulley 14, mounted on the upper part of the frame 6, and thence to a lever 4, whose lower extremity is fulcrumed on a cross-bar 6 of the frame 6. The bar 6 is located a short distance below the top bar 6. The levers 4 are arranged a suitable dis tance apart, and the chain 12, which passes upwardly on the right, is connected with the lever A farther to the left, While the left-hand I chain 12 is connected with the right-hand lever 4. Each lever is provided with a cooperating notched quadrant 16 of ordinary construction. By means of these levers the frame part 6 may be raised and lowered one side at a time on the standards 9 of the axles 8. To raise the right-hand side of the frame 6, referring to Fig. 4:, the left-hand lever is pulled toward the left, while to raise the. left-hand side of the frame 6 the right-hand lever 14 is pulled toward the right. 17 is attached to the top of the frame 6 and extends above the same. This bar strength? ens the structure. 7

The rear extremities of the arms 5 of the framework are supported above the axle 18, (see Fig. 3,) upon which the large groundwheel 19 is journaled. The extremity of the axle remote from the wheel 19 is secured to A U-shaped bar an upright bar 2, in which is slidable vertically a bar 20, whose lower extremity is rigidly connected with a stub-axle 21, upon which the smaller ground-wheel is journaled. By loosening or removing the bolts 3, which connect the framebar 2 with the bar 20, the rear part of the frame may be adjustable vertically on the bar 20. This may be necessary when the machine is running on a side hill or for any reason the wheels 19 and 22 occupy surfaces in different horizontal planes.

Mounted on the rear axle 18 is a depending guide 37, through which the rear extremity of the plow-beam 23 passes. This plow-beam is located beneath the framework 5. The plow 26 is rigidly secured to this beam intermediate its extremities. The plow is provided with a bar 26, which extends upwardly above the beam and passes through a guidestrap fast on the upper framework 5. The rear portion of the moldboard 26 of the plow is curved to cause the dirt to pass upwardly to the apron of an endless carrier or elevator 27 instead of passing off to one side, as the dirt is thrown by a moldboard of ordinary construction. Thisresultisobtained bycurving the free edge of the moldboard upwardly, as shown in Fig. 8. The forward extrem1ty of the plow-beam is vertically movable on an upright bar A, whose lower extremity is pivoted in a short plate B, extending rearwardly from the frame-bar 6, to which it is attached. The bar A passes through an opening in the forward extremity of the plow-beam, while its upper extremity is pivoted in a projection B, extending rearwardly from the bar 6. Above the part B the barA terminates in an eye A, which is connected with a U-shaped part D, rigidly secured to the frame-bar 5. This construction permits of sufficient movement between the plow-beam and the frame 6 to allow the machine to be turned when a team is hitched to a tongue E. The latter is secured to a frame part 6 as shown at 24. The opening in the plow-beam through which the bar A passes is provided with inclined walls, the opening being largest at its upper extremities to permit the lateral tilting of the frame 6 without interfering with the position of the beam. (See Fig. 11.) The forward extremity of the plow-beam is connected with two chains 28 and 29, whose rear extremities are attached to the periphery of a grooved pulley 30 at different points, one above and the other below the axis of the pulley. The chain 28 passes over the top of the pulley and the chain 29 underneath the pulley. This pulley 30 is journaled on the upper framework 5. The chain 28 passes forwardly from this pulley over a small guide-pulley 31 and thence downwardly, its lowerextremity being directly connected with the forward extremity of the plow-beam. The other chain 29 passes forwardly from its pulley over a small guide-pulley 32, thence downwardly under a guide-pulley 33, and thence upwardly to the forward extremity of the plow-beam, to which it is made fast. The pulley 30 is made fast to a rock-shaft, to which is secured the lower extremity of a hand-lever 34, arranged to codperate with a notched quadrant 35. The guide-pulleys 31 and 32 are mounted on the forward extremity of the frame-bar 5, while the pulley 33 is mounted on the projection B of the bar 6. As the lever 34 is moved rearwardl y or toward the right (referring to Fig. 2) the forward e'xtremity of the plow-beam is raised, while when said lever is moved in the opposite direction the forward extremity of the plowbeam is lowered. The two chains when operated as aforesaid hold the plow-beam in the adjusted position, the one preventing it from moving upwardly and the other from moving downwardly, as will be readly understood.

The rear extremities of the frame-bars 5 are mounted on the frame parts 35 and 36, supported by the axle 18. The rear extremity of the plow-beam is vertically movable in a depending guide 37, mounted on the framework, and is controlled through the instrumentality of a wheel 38, journaled on the frame, and two chains 39 and 40, the one being connected with the periphery of the wheel above its axis and the other below its axis. The chain 39 passes over a pulley 41, mounted on the frame, and thence downwardly, its lower extremity being connected with the rear extremity of the plow-beam, as shown at 42. The chain 40 passes over a pulley 43, thence downwardly under a pulley 44, and thence upwardly, its extremity being connected with the plow-beam, as shown at 45. The wheel 38 is operated by a lever 46, cooperating with a notched quadrant 47. As the lever is moved in the direction indicated by the arrow in Fig. 5 the rear extremity of the plow beam is raised by the chain 39. When properly adjusted, the chain 39 holds it against further downward movement, while the chain 40 holds it against upward movement.

Pivotally mounted on the rear extremity of the plowshare and projecting thereunder is an elevator or carrier frame 48, whose upper extremity is suitably supported on the framework. Journaled in this frame are rollers 49, supporting an endless carrier 50, the fabric of which is strengthened and shaped to hold the dirt by transverse metal strips 51. This carrier is operated from the large rear wheel 19, which is provided with afast gearwheel 52, meshing with a pinion 53, fast on a transverse shaft 54, to which is made fast a sprocket-wheel 55, connected by a chain 56 with a sprocket 57, fast on a journal of a drum or roller 57 at the upper extremity of the carrier-frame. The shaft 54 is journaled on the rear upper portion of the framework and is provided with a bevel-gear 58, meshing with a similar gear 59, fast on a short shaft 60, whose extremity remote from the gear 59 is provided with a sprocket-wheel 6]., which is IIO connected by a chain 62 with a sprocket 63, fast on the journal extension of a roller or drum 64, journaled in the upper extremity of the side bars 65 of the frame of an inclined elevator or carrier 66, extending at right angles to the carrier 27. The lower extremity of the carrier 66 occupies a position underneath the upper extremity of the carrier 27, whereby the dirt discharged from the upper extremity of the one carrier falls on the lower extremity of the endless apron 67 of the other carrier. This apron is supported by rollers 68, journaled in suitable boxes mounted on the frame-bars 65.

An arm 69, whose lower extremity is made 7 fast to the stationary framework of the machine, extends upwardly and is then bent rearwardly nearly at right angles and projects over the carrier 66. The rearward ex tremity of this arm 69 is supported by braces 70, 71, and 72, whose upper extremities are connected directly with the said arm 69 and whose lower extremities are secured to the frame. The brace 72 extends downwardly from the frame, as shown at 72, and is then bent abruptly upward. Near the angle of this bend a box or bracket 73 is mounted on the part 72 of the brace. This bracket supports one extremity of a rod or bar 74, whose opposite extremity is supported in a hanger 75, depending from the stationary framework of the machine. (SeeFig. 3.) From the rearward extension of the arm 69 lead two bars 76 to the bars of the carrier-frame. These bars 76 form the support for the outer extremity of the carrier 66.

When the apparatus is in use, a team is hitched to the tongue E and the plow-beam properly adjusted. The driver occupies a position on the seat F, while the person'who operates the levers 34 and 46 whereby the plow-beam is raised and lowered stands on a platform H,supported by the upper framework. As the plow passes through the ground the abrupt curve of the moldboard causes the dirt to pass rearwardly to the apron of the carrier 27, whereby the dirt is carried upwardly and discharged on the lower extremity of the apron 67 of the carrier 66, whereby it is carried laterally and discharged in a wagon or other suitable receptacle. (Not shown.)

Both carriers 27 and 66 are provided with transverse metal strips 51, which are bent to give them the dished appearance shown in Fig. 12 while they are in the carrying position.

Having thus described my invention, what I claim is- 1. In a grading-machine, the combination with a suitable framework, of a plow whose moldboard is curved upwardly at its outer edge to prevent the dirt from passing over said edge, whereby the dirt is made to pass over the rear edge of the moldboard as the machine moves forward, a beam to which the plow is secured, and a depending stirrup shaped guide through which the rear extremity of the plow-beam passes, and means connected with the front and rear extremities of the 2.
